Our Recommendation


  • Cover ground areas with dust sheets & tape where necessary.
  • Scrape & dust down all surfaces for painting.


  • Apply one coat of  primer, leave dry over 16 hours.
  • Sand, dust down & apply one undercoat leave dry over 16 hours.
  • Dependant on skill level, a 2nd undercoat may be necessary.
  • Apply one coat of gloss, leave dry as long as possible before closing areas.
  • Re-open areas frequently for a few days, so wood jambs can thoroughly harden.

*Always remove masking tape after a few days because the tape glue may dry and damage the fittings.
